Praxis Agriculture (5701) Practice Exam

Cleaning and sanitizing serve different purposes: cleaning removes soil particles from surfaces, while sanitizing reduces the number of microorganisms to safe levels. Cleaning uses detergents and water to physically lift away dirt and debris, including what can shield germs. Sanitizing comes after cleaning and uses chemical sanitizers or heat to lower microbial counts to acceptable standards. Because soil must be removed first for sanitizers to work effectively, this two-step approach—cleaning then sanitizing—is the best description of how these practices differ. The other statements mix up the roles: sanitizing does not remove soil, cleaning isn’t about killing all bacteria, and cleaning isn’t defined by heat killing microbes.
